[Ngon Plugin] Can't get screw holes in a reciprocal structure

It’s all about screw holes.gh (28.7 KB)

I try to make cross joints and screw holes on a reciprocal timber structure using the Ngon plugin.

I made the joints and got the final result in mesh form.
But I can not get the Brep result with the screw holes(using the Tile_NN_Screw component).
It seems like I have got the right Elements and Cutters, but when I feed it into BrepBooleanDiff, the result is not there.

I try to follow the Ngon example files to solve this problem for almost 4 hours, but couldn’t. Please help! And If you know any tutorial or article on how to use Ngon to make joints, please share, Thank you!

@Petras_Vestartas Hi, Would you like to help me with this one? Thanks!

Wihout using brep boolean. Did you try to cut joint using typical brep boolean difference?
That component does the same just in a parallel thread.

Try to do it for one beam. This week is super busy for me. I could find more time maybe next one;)

Thank you! I solved the problem following your advice.

For whom has the same issue, see the GH below.

HI @Quan_Li, I opened your script but faced an issue with the BrepBooleanDiff Component. Do you know why this is so? I am opening the file in R8. Or perhaps @Petras_Vestartas, you could advice on this.
